Q1: Who has never used R?

Q2: Who mainly uses R for ggplot2?

Q3: Who is left?

Why R?

What is an R package?

“In R, the fundamental unit of shareable code is the package. A package bundles together code, data, documentation, and tests, and is easy to share with others.” (Wickham, 2015)

Motivation

• High demand for ‘pieces of script’
• Convinced it can make life easier for researchers
• Similar efforts by other model teams, e.g. various MagPIE packages
• Keen to learn how to build an R package

Purpose of rglobiom (to be discussed)

• Provide functions to facilitate GLOBIOM pre/post processing tasks
• Provide documentation and examples on how to do this
• Offer a central location for GLOBIOM related info that is nowhere to be found (e.g. list of simus, fm/dm conversion factors, standard crop names, etc)
• …?

Package contents

Historical trends & projections

EU NUTS map

GLOBIOM 30 region map

LUID map

How does it work?

Link

Need to decide on:

• Fixed location of base maps
• Fixed location of OUTPUT_FAO.gdx
• Standard GLOBIOM nomenclature
• Location of R support scripts
• Limited number of scenario columns

Maintenance, updates and extensions

• Project in the IIASA Github repository
• Easy to extent and generate documentation

Next steps?

• Please try and provide feedback
• Is there anything else that should be added?

Thank you
